KXl'D ANDERSEN 



(192) 



Rh. andreinii needs only comparison with Rh. blasii and 

 Rh. ernpusa From Rh. blasii ( 2 ) it differs as follows: — 



(1) The ears are a little shorter and narrower. (2) The lateral 

 margins of the deltoid sella are almost quite evenly converging 

 from base to tip; on very close examination a faint indication of 

 a constriction at the middle is observable; in Rh. blasii the sella 

 is abruptly constricted at the middle ( 3 ). (3) The horse-shoe will 

 probably, when a larger series is available, prove to be a little 

 broader, at least on average. (4) There is scarcely any difference 

 in the shape of the skull, but it would seem that in andreinii 

 the cranium is on the whole a little more slenderly built, and 

 the anterior maxillary widtli (across the cingula of the canines) 

 slightly smaller. 



p 3 is situated in the tooth-row, but somewhat towards the 

 external side ; p., and p 4 therefore distinctly separated, p 2 quite 

 in row, with a distinct cusp, pointing inwards. — This dentition 

 is as in Rh. blasii, with the only exception that in all the skulls 

 of this latter species I have seen p 3 is pushed more definitely 

 towards the external side of the row (half external or almost 

 quite external). 



Rh. andreinii is evidently more closely related to Rh. empusa. 

 The two species agree in the shape of the sella and the size of 

 the ears. But the horse-shoe is markedly broader in Rh. empusa. 

 The skull is of the same size, but the parietal region in andreinii 

 less globular. Dentition quite as in empusa. 



Affinities. — The Rh. empusa type lias originated from 

 a bat of the Oriental minor-subbadius type ( 4 ). We now know 

 three modifications, viz. —

(*) Specimens of Rh. blasii examined: — 2 cf ad., 1 Q ad. (in ale); Cave of Adul- 

 lam, Jerusalem; collected by Canon II B. Tristram (B. M. no. 61. 8. 17. 52-54). — 4 

 Q ad. Ciii ale); Lekara, Cyprus, April 1894; presented by Lord Lilford (B. M. no. 94. 

 12. 1. 1-4). — Jun. (skin); Mokran Coast, Aug. 1877: collected by Capt. C. J. Bingham; 

 presented by A. O. Hume, Ksq, (B. M. no. 85, 8. 1. 112). — Ad. (skin); Syria (B. M. no. 

 76, 10. 20. 3). — 4 skulls, from all the localities enumerated. 



('•) In Senna's excellent original account of Rh. andreinii (1. s. c.) the sella is 

 described as pointed at summit, whereas in Jill, blasii it is « pill largo e arrotondato » 

 (see also pi. XVIII. figs. 9 and 17, in Senna's memoir). I fail to see any difference in 

 this respect between the two species; in all the examples of Rli. blasii to hand the 

 sella is as pointed as in andreinii. — Dobson's figure of the sella of Rli. blasii (Cat. 

 Chir. Brit. Mus. pi. VII. lig. 7; 4878) is misleading; the constriction is by far not 

 sufficiently emphasized; the side-view of the nose-leaves (1. c. lig. 7 a) is, as already 

 pointed out by Senna, rather badly drawn.
